Abstract
Description
[Technical field]
[0001] The present invention belongs to the field of medicinal chemistry, and specifically relates to FAK inhibitors and combination drugs thereof. [Background technology]
[0002] Focal adhesion kinase (FAK) is an intracellular non-receptor tyrosine kinase that was first discovered in transfected V-Src chicken embryo fibroblasts. FAK is highly expressed in many tissues, and its protein sequence has high homology among many species (e.g., rats, toads, and humans). FAK is involved in multiple biological processes such as tumor formation, proliferation, metastasis, apoptosis, and cardiovascular disease, and is an anti-tumor target that is currently attracting widespread attention.
[0003] Recent studies have revealed that FAK is activated by various factors, such as integrins and G protein-coupled receptors, and that FAK regulates signaling pathways such as P53 and PI3K-AKT-mTOR in cells through two pathways, kinase-dependent and kinase-independent, and is involved in biological processes such as tumor cell survival, proliferation, and metastasis. The first attempt aimed to suppress tumors by downregulating the expression of FAK in tumor cells. Transfecting carboxy-terminal inactivated FAK (FAK-CD) to silence FAK and reduce cell adhesion and proliferation resulted in the inhibition of breast cancer cell proliferation in in vivo experiments. Transfecting a plasmid containing FAK-silenced RNA (FAK-siRNA) also suppresses cancer in vivo. At the same time, the expression of FAK and FAK downstream signal molecules (e.g., SRC) can be suppressed to enhance antitumor effects.
[0004] Due to the important function of FAK in tumor cells, the reliability of gene transfection, and the consideration of the safety of viral vectors, small molecule inhibitors based on the FAK signaling pathway have emerged and have achieved good results in recent years. At present, several FAK inhibitors are used as antitumor drugs and are in the stage of preclinical research or clinical trials. In the literature ("Research progress on antitumor new target focal adhesion kinase FAK and its inhibitors", Chen Ying et al.), it has been reported that TAE226, also known as NVP-226, can inhibit FAK activity by blocking the binding site of FAK and ATP, and the phosphorylation sites of Y397 and Y861 of FAK. However, the field still needs to develop FAK inhibitors with better inhibitory activity or better pharmacodynamic properties.
[0005] Deuterated drugs refer to drugs in which some hydrogen atoms in the drug molecule are replaced with deuterium. Deuterium (D) is a stable isotope of hydrogen. The form and volume of deuterium in drugs are basically the same as those of hydrogen, so even if some hydrogen atoms in drug molecules are replaced with deuterium, the activity of the drug molecule will not change. In addition, the mass of deuterium atoms is twice that of hydrogen, so the zero-point vibration energy of the carbon-deuterium bond (CD) is lower than the zero-point vibration energy of the carbon-hydrogen bond (CH), and the carbon-deuterium bond is more stable. Therefore, by replacing some hydrogen atoms in drug molecules with deuterium, the decomposition process of the drug can be delayed, allowing the deuterated drug to act longer in the body, and achieving the purpose of changing the drug metabolism rate or metabolic pathway, thereby improving the pharmacokinetics and reducing the metabolic toxicity of the drug. In view of the important applications of FAK inhibitors in the field of tumor treatment and their limitations, we have combined the technology of deuterated drugs to find new molecular entities, reduce the impact on liver and kidney function, and improve the safety and Improving the efficacy and efficacy of this class of drugs is a research trend that will drive further development of this class of drugs, and its application is of great value.
[0006] Although drug combination is an effective way to improve therapeutic efficacy, there have been no reports of combining deuterated FAK inhibitors with other anticancer drugs or methods. Summary of the Invention

[0091] 2.PAN02 Tumor Model (1) Test method PAN-02 cells in the logarithmic growth phase were harvested, washed twice with PBS, and then resuspended in pre-cooled PBS for inoculation. The experimental animals were female C57BL / 6 mice purchased from Beijing Weitong Lihua Laboratory Animal Co., Ltd. The C57BL / 6 mice were adapted to the laboratory environment for 3 days and then subcutaneously inoculated with PAN-02 cells in the right flank, with the inoculated cell volume being 1 × 10 6 The tumor size was approximately 100 mm 3 After they had grown to adulthood, they were screened and randomly divided into groups of 8 mice each, and administered according to the groups and administration schedules in Table 4 below. The day they were divided into groups and administered was defined as day 1, and the administration period was 33 days.
[0092] [Table 4]
[0093] (2) Test results The efficacy after 33 days of administration to animals is shown in Figure 2, and the calculated tumor inhibition rates are shown in Table 4. When compound 44 was administered in combination with mPD-1 antibody (Group 5), the tumor inhibition effect was significantly improved compared to when compound 44 was administered alone (Group 4) or mPD-1 antibody was administered alone (Group 2).
[0094] On the other hand, when compound 44 of the present invention (25 mg / kg, administered twice a day) was administered in combination with mPD-1 antibody (Group 5), the tumor suppression effect was significantly improved compared to when Defactinib (50 mg / kg, administered twice a day) was administered in combination with mPD-1 antibody (Group 3). That is, when administered in combination with a PD-1 inhibitor, the compound of the present invention exhibited a superior tumor suppression effect at a lower dose than Defactinib, indicating that the combination of the compound of the present invention and a PD-1 inhibitor has a significantly superior antitumor effect against the PAN-02 tumor model than the combination of Defactinib and a PD-1 inhibitor.
[0095] As described above, the present invention provides deuterated compounds that exhibit better pharmacokinetics, higher maximum blood concentration, higher exposure, and longer half-life, and have better metabolic performance, compared to undeuterated compounds. Furthermore, the deuterated compounds of the present invention can effectively inhibit the activity of FAK, and are useful for the preparation of FAK inhibitors and / or drugs for treating cancer. At the same time, the deuterated compounds of the present invention can exert synergistic effects in combination with anticancer drugs (such as PD-1 inhibitors), significantly improving the tumor suppression effect and providing a better option for clinical cancer treatment.
